The qview spatial tool using rotated rectangle selection crashes when selecting a small area.

I've tested this on two cubes.
/usgs/cpkgs/isis3/testData/isis/src/base/apps/crop/tsts/sinu/input/mapsinu.cub - crashes when selecting 5 pixels or less
/usgs/cpkgs/isis3/testData/isis/src/base/apps/isis2pds/tsts/default/truth/ab102401.cub - crashes with 2 pixels or less

It is not crashing any more however I found another issue with the tool that may actually be the root cause of this crash. It looks like the tool is not calculating the area or average correctly. I will make a new ticket for the new issue. Please do not move forward on this ticket until you have talked to Stuart.
